ChuHan
ChuHan is a historical period in Chinese history that refers to the period of the Warring States (475-221 BC) and the Qin Dynasty (221-206 BC). The name "ChuHan" is derived from the two most prominent states during this time: Chu and Han. The Chu state, centered in modern-day Hubei province, was one of the most powerful and influential states during the Warring States period. The Han state, centered in modern-day Henan province, was another major power and eventually rose to dominate the other states. The ChuHan period is significant for its political, military, and cultural developments, which laid the groundwork for the unification of China under the Qin Dynasty. The Qin Dynasty, founded by Qin Shi Huang, successfully unified China in 221 BC, marking the end of the ChuHan period and the beginning of the Qin Dynasty. The ChuHan period is also notable for the development of Confucianism, Taoism, and Legalism, which had a profound impact on Chinese philosophy and culture.
